Abstract
The utility model relates to a kind of agitator, be particularly related to a kind of gas-liquid mixed agitator, a kind of gas-liquid mixed agitator, include rotating disc and the circumference uniform distribution blade on rotating disc, the concave surface of described blade is a stress surface, it has the leading edge of the lordosis that turns up, and the protuberance summit is near rotating disc center one side, the leading edge of vane stress face is set as not straight flange shape, thereby increased the shearing force of gas, thereby more help breaing up of bubble, a material material, increased mixing effect.
Description
Technical field
The utility model relates to a kind of agitator, particularly a kind of gas-liquid mixed agitator.
Background technology
The gas-liquid mixed agitator, gas-liquid mixed as fermentation tank, all be that compressed air is introduced from container bottom, stir through agitator, make the increase that contacts of gas and material, but tool is than the gas-liquid mixed agitator of prismatic blade structure at present, usually it is relatively poor that it holds the gas ability, and bigger blade of curvature such as semi-canal type, hyperboloid formula though that it holds the gas ability is stronger relatively, thereby have been improved dispersion and mass transfer effect, but the agitator of common this blade of tool, its shear ability descends to some extent, is unfavorable for breaing up of bubble, material particles, thereby influences mixing effect.Present in addition its rotating disc of gas-liquid mixed agitator all is flat, this makes the very fast meeting of gas spread out around rotating disc, make gas very brief with the time of contact of material in whipping process, cause mixing effect not ideal, be unfavorable for the abundant reaction of material and gas.
Summary of the invention
The purpose of this utility model is the deficiency that solves above-mentioned gas-liquid mixed agitator, and provides a kind of mixing effect good gas-liquid mixed agitator.
The purpose of this utility model is achieved by the following technical solution: a kind of gas-liquid mixed agitator, include rotating disc and the circumference uniform distribution blade on rotating disc, the concave surface of described blade is a stress surface, it has the leading edge of the lordosis that turns up, and the protuberance summit is near rotating disc center one side.
The utility model further is set to again: the leading edge of described lordosis is a triangle.
The utility model further is set to: described blade is parabolic blade, is the both sides up and down that boundary's branch is positioned at rotating disc with the parabola top, and parabolic upside is longer than downside.
The beneficial effects of the utility model are: the leading edge of vane stress face is set as not straight flange shape, thereby increased the shearing force of gas, thereby more help breaing up of bubble, a material material, increased mixing effect.

The specific embodiment
Now in conjunction with the accompanying drawings the utility model is further described:
As shown in Figure 1 to Figure 3 as can be known, a kind of gas-liquid mixed agitator of the utility model embodiment, include a kind of gas-liquid mixed agitator, include rotating disc 1 and the circumference uniform distribution blade 2 on rotating disc, the concave surface 21 of described blade 2 is a stress surface, it has the protruding leading edge 3 of turning up, and protuberance summit 31 is near rotating disc center one side.Usually tool is than the gas-liquid mixed agitator of prismatic blade structure; it is relatively poor that it holds the gas ability; and bigger blade such as the semi-canal type of curvature; the hyperboloid formula; though it is stronger relatively that it holds the gas ability; thereby make the reaction of material and gas more abundant; but the air and liquid mixer of common this blade construction of tool; its shear ability descends to some extent; be unfavorable for bubble; breaing up of material particles, thus mixing effect influenced, and the edge adopts not straight convex and summit near rotating shaft center in face of the vane stress; the shearing force of blade inboard is strengthened; thereby increased the shearing force of whole agitator, more helped bubble; breaing up of a material material makes mixing effect desirable more; therefore present embodiment adopts this scheme; certainly, if adopt general structure blade, also obviously in this practical protection domain.
Described protruding leading edge 3 is a triangle.Leg-of-mutton protruding leading edge other shape relatively makes manufacturing easier, and can certainly adopt other shape such as quadrangle.
Described blade 2 is parabolic blade, is the both sides up and down that boundary's branch is positioned at rotating disc with the parabola top, and parabolic upside is longer than downside; Paraboloidal blade is to be bent into the blade that the cross section becomes parabolic shape by sheet material, can reduce the air pocket at blade rear, blade is an asymmetric formula up and down, the blade on top is longer than the blade of bottom, the gas of rising is covered by the linear leaf on top, avoided too early directly the rising of gas to escape from the impeller zone, thereby make the reaction of material and gas more abundant, further improved mixing effect, certainly blade also can be other shape, and adopt parabolic shape desirable more, so present embodiment adopts parabolic shape as shown.
Described rotating disc 1 is the middle pot cover shape that arches upward; the rotating disc 1 of pot cover formula more helps increasing the holdup time of gas under dish; thereby material and gas are reacted fully, certainly, if adopt flat rotating disc undoubtedly also within this practical protection domain.
Claims (3)
